Well, whether you call these cool or not is probably up to you, but
you find simple but hopefully "cool" examples on the OPS web site:




And we are working on more. Note also the XForms sandbox, which allows
you to try your own XForms examples from the comfort of your Firefox
or IE browser ;-)


(Remember OPS 3.0 is still in beta.)

Good! This is where implementors should work to make such examples
work on their own platforms, agree on extensions if necessary, etc.

Amen to that.

This point was a very important part of our talk at XTech 2005 back in
May. See the whole article here:


In particular, notice this quote: "Another interesting perspective on
Ajax and XForms is that an Ajax-based XForms implementation can well
be considered a standard way of creating Ajax-based applications!
While there are today client-side libraries that implement Ajax
functionality in the user agent, their scope is usually quite limited:
it does not address how updates to the HTML page are performed, for
example. With XForms, writing Ajax-based applications implementing a
number of Ajax scenarios can be done by sticking to a well-established

Welcome to the club! If projects like FormFaces, FormsPlayer, Chiba,
Firefox, and our Orbeon PresentationServer (OPS) work together on
interoperability, I believe the result will be positive for XForms,
and for all those projects as well, as the market for XForms will
